My 6c on the new 2.1.4 firmware is thankfully every area that was slow on 2.1.1 is now impressively fast, including returning to the home page, and browsing and editing shelves ( also enjoying the new functional improvements) , and lastly sideloaded epub page turn speeds are at least comparable to 2.1.1 and placebos aside may be back to 1.9.17 levels. Well done Kobo ! Scooby snacks duly awarded .
